Sandwich PK Technique for Eyes with High Risk of Elevated Posterior Pressure

Some eyes, such as in babies, are at especially high risk of elevated posterior pressure during penetrating keratoplasty (PK), considerably increasing the likelihood of expulsion of the lens. In this video, Dr. Christopher Rapuano describes a technique where the donor button is sutured over the recipient cornea, which eliminates the open-sky time and significantly decreases the chance of expulsion of intraocular contents.
